Various apparatuses or processes will be described below to provide anexample of an embodiment of each claimed invention. No embodimentdescribed below limits any claimed invention and any claimed inventionmay cover processes or apparatuses that differ from those describedbelow. The claimed inventions are not limited to apparatuses orprocesses having all of the features of any one apparatus or processdescribed below or to features common to multiple or all of theapparatuses described below. It is possible that an apparatus or processdescribed below is not an embodiment of any exclusive right granted byissuance of this patent application. Any invention disclosed in anapparatus or process described below and for which an exclusive right isnot granted by issuance of this patent application may be the subjectmatter of another protective instrument, for example, a continuingpatent application, and the applicants, inventors or owners do notintend to abandon, disclaim or dedicate to the public any such inventionby its disclosure in this document.

Referring to FIG. 1, an exemplary kit of parts 100 for preparing a cakeis shown. The kit of parts includes a core mold 102, and a finishingmold 104. The core mold 102 may be used for preparing the core of thecake. For example, the core mold may be a cake pan that is made fromaluminum, cast iron, stainless steel, non-stick coated metal, or hightemperature food-grade silicon, and may be used for preparing a cakecore such as a flour-based baked product. In the example illustrated,the core mold 102 is a generally star-shaped cake pan which may be usedin accordance with known methods to bake a generally star-shaped cakecore.

Referring still to FIG. 1, the finishing mold 104 may be used forfinishing the cake, for example for applying a finishing compound suchas icing to the cake, as will be described in further detail below. Inthe example shown, the finishing mold 104 has a volume (also referred toas a “finishing mold volume”) that is greater than the volume of thecore mold 102 (also referred to as a “core mold volume”), and isgenerally shaped to receive the cake core. For example, as shown, boththe finishing mold 104 and the core mold 102 are star-shaped, and thefinishing mold 104 has a volume that is between about 5% and 25% greaterthan the volume of the core mold 102, and more specifically betweenabout 18% and 22% greater than the volume of the core mold 102. In oneparticular example, the volume of the finishing mold 104 may be about20% greater than the volume of the core mold 102. This can allow for acake produced with the kit 100 to have a volume of icing that is about20% of the volume of the cake core.

In other examples, both the core mold and the finishing mold may beother shapes. For example, both the finishing mold and the core mold maybe round, square, rectangular, or a more complicated shape. In furtheralternate examples, the core mold and the finishing mold may be of adifferent shape from each other.

Referring to FIGS. 1 and 2, in the example shown, the finishing mold 104includes a support layer 106 and a lining layer 08. The support layer106 is generally stiff and rigid. For example, the support layer 106 maybe made from aluminum, steel, steel coated with a non-stick compound, orsuitably thick food-grade silicon. The lining layer 108 is generallyflexible. For example, the lining layer 108 may be made from food-gradesilicon having a wall thickness of between about 0.10 inches and 0.15inches. In other examples, the lining layer may be of another thickness.

Referring to FIG. 2, the lining layer 108 is receivable and nestable inthe support layer 106, so that the outer surface 1 0 of the lining layer108 generally faces and contacts the inner surface 112 of the supportlayer 106.

Referring to FIGS. 3 to 9, an exemplary series of steps for preparing acake with the kit 100 of FIG. 1 is shown. Referring first to FIG. 3, thecore mold 102 (shown in FIG. 1) may be used to prepare a cake core 114.For example, the cake core 114 may be flour-based, and may be baked inthe core mold 102. The cake core 114 may then be removed from the coremold 102 and may optionally be hardened, for example by cooling orfreezing the cake core 114. Referring to FIG. 4, a finishing compound116 may be applied to the finishing mold 104, and more specifically, tothe lining layer 108 of the finishing mold 104. The finishing compound116 may be, for example, an icing or frosting. In some particularexamples, the finishing compound 116 may be a putty icing. The puttyicing may be a generally thick icing that is prepared similarly to abuttercream icing, but that is kneaded instead of whipped, such that itcontains less air and is less fluffy. In some embodiments, the finishingcompound 116 includes edible clay or gum paste. Other examples offinishing compounds are described below. An excess of the finishingcompound 116 may be applied to the lining layer 108 (e.g. a volume thatis more than 20% of the volume of the cake core 1 14), and may be spreadabout the lining layer 108. The lining layer 108 may be tapped to removeair between the finishing compound 1 16 and the lining layer 108.Referring to FIGS. 5 and 6, the hardened cake core 1 14 may be insertedinto the finishing mold 104 and pressed into the finishing compound 116, so that the bottom surface 118 of the cake core 1 14 is generallyflush with the bottom edge 120 of the finishing mold 104. Any excessfinishing compound 1 16 that is pressed out of the finishing mold 104may be scraped away. The finishing compound 1 16 may then optionally behardened. For example, the finishing mold 104, containing the finishingcompound 1 16 and the cake core 1 14, may be cooled or frozen. Thefinishing mold 104 may then be removed from the cake. Referring to FIG.7, in order to remove the finishing mold 104, the support layer 106 mayfirst be removed from the lining layer 108, for example by lifting itoff of the lining layer 108. Referring to FIG. 8, the lining layer 108may then be peeled off of the hardened finishing compound 1 16, to yielda finished cake 122, as shown in FIG. 9.

Referring now to FIG. 10, the kit 100 may optionally include one or moredecoration accessories 124. In the example shown, the decorationaccessory 124 is an insert which includes a generally flat thin sheet126 having a decorative feature 128 formed therein. The decorativefeature 128 includes a mold 130 for text stating “Happy Birthday”. Thesheet 126 is shaped and sized to match the base 132 of the inner surface134 of the finishing mold (shown in FIG. 1), which in the example shownis star-shaped. In use, a finishing compound, such as an icing of adifferent color than the icing used to finish the remainder of the cake,may be spread onto the sheet 126, so that it fills the mold 130 for thetext. The excess icing may then be scraped away, so that the mold 130for the text remains filled with icing, but the remainder of the sheet126 is generally free of icing. Prior to applying the finishing compound1 16 to the finishing mold 104 (i.e. prior to the step shown in FIG. 4),the insert may be inserted into the finishing mold 104, so that it restson the base 132 of the inner surface 34 of the finishing mold 104. Themethod may then proceed through the steps shown in FIGS. 4 to 8. Afterthe lining layer 108 is peeled away, the insert may be peeled off of thecake, imparting the text “Happy Birthday” to the top of the cake inicing.

In alternate examples, inserts may include alternate decorativefeatures, and may be shaped and sized to be used on another part of thecake, such as on the side wall of the cake, rather than on the top.

In further alternate examples, decorative features may be formeddirectly in the lining layer of the finishing mold.

In a further alternate example, the finishing compound may be applied tothe finishing mold, and then may be hardened before it is applied to thecake core. A generally soft transition layer of finishing compound (e.g.a room temperature icing) may then be applied to the cake core and/orthe hardened finishing compound. The cake core may then be inserted intothe finishing mold, so that the cake core, transition layer, andhardened finishing compound are pressed together, with the transitionlayer acting to adhere the cake core and finishing compound together.The finishing mold may then be removed from the cake core, transitionlayer, and hardened finishing compound.

As mentioned above, kits as described herein may be used to formfinished cakes of relatively complicated shapes. An exemplary kit 200useable to form a cake of a complicated shape is shown in FIGS. 11 to12. In FIGS. 11 to 12, similar features to FIGS. 1 to 10 are labeledwith similar reference numerals to FIGS. 1 to 10, incremented by 100. Inthe example of Figures and 12, the kit 200 is useable to form apumpkin-shaped cake 222 (shown in FIG. 12). Referring to FIG. 11, thekit 200 includes three sets of core molds 202 a, 202 b, 202 c, and threecorresponding finishing molds 204 a, 204 b, and 204 c. The first coremold 202 a and first finishing mold 204 a are useable to form the mainpart of the pumpkin. The second core mold 202 b and second finishingmold 204 b are useable to form the stem of the pumpkin. The third coremold 202 c and third finishing mold 204 c are useable to form a plaquestating “Happy Halloween”. Each core mold 202 a-c and correspondingfinishing mold 204 a-c may be used as described above with respect toFIGS. 3 to 9 to respectively form a finished pumpkin body, a finishedpumpkin stem, and a finished plaque, which may be assembled together toform a pumpkin-shaped cake 222 (shown in FIG. 12).

Referring to FIG. 11, the kit 200 further includes two decorationaccessories 224 a, 224 b. The decoration accessories 224 a, 224 b aresimilar to the decoration accessory 124 described above, and eachincludes a generally flat thin sheet 214 a, 214 b, respectively, havingdecorative features 216 a, 216 b, respectively, formed therein. Thefirst decoration accessory 224 a includes a mold 230 a for leaves of thepumpkin. The second decoration accessory 224 b includes a mold 230 b forthe facial features of the pumpkin. In this example, rather than beingused as an insert in the finishing mold 204, the decoration accessories224 a, 224 b are useable to form decorative features which may beapplied to the cake after the cake is removed from the finishing mold204. For example, icing may be spread onto the sheets 214 a, 214 b suchthat it fills the molds 230 a, 230 b. The excess icing may then bescraped away, so that the molds 230 a, 230 b remain filled with icing,but the remainder of the sheets 214 a, 214 b are generally free oficing. The icing may then be hardened, for example by cooling orfreezing the sheets 214 a, 214 b. When the icing has hardened, thedecorative features may be removed from the molds 230 a, 230 b, andapplied to the cake.

In the example shown, the finished cake 222 also includes decorativevines 236, which may be added to the finished cake with the use of apiping bag.

In alternate examples, rather than using a mold to form decorativefeatures, decorative features may be formed, for example, by manuallycutting features from a pre-formed sheet of icing.

Referring now to FIGS. 13A to 14B, another example series of steps forpreparing a cake is shown. In FIGS. 13A to 14B, an alternate example ofa finishing mold 304 is shown, and similar features to FIGS. 1 to 10 areidentified with like reference numerals incremented by 200.

Referring to FIGS. 13A and 13B, in the example shown, the finishing mold304 includes injection ports 338 extending therethrough. The injectionports 338 extend through the finishing layer 308 and the support layer306. A finishing compound may be injected through the injection ports338, as will be described below.

Referring to FIGS. 13A and 13B, in use a cake core 314 may be prepared(for example with a core mold as described above), and may be placed ona seal 342. The seal 342 may be a generally planar member that is sizedto cover and seal the opening 344 of the finishing mold. The cake coremay then be inserted into the finishing mold 304, for example by placingthe finishing mold 304 over the cake core 314, so that the cake core 314is received in the finishing mold 304 and so that the finishing mold 304rests on the seal 342. The finishing mold 304 and the seal 342 may thenbe engaged so that they are generally sealed together. For example,pressure may be applied to the finishing mold 304 to force it downwardlyonto the seal 342. Alternatively, one or more locks may be provided forsecuring the finishing mold 304 to the seal 342. Alternatively, a vacuummay be used to force the finishing mold 304 and the seal 342 together.

Referring to FIGS. 14A and 14B, a finishing compound may then be appliedto the finishing mold 304. For example, a finishing compound may beinjected into the injection ports 338, so that it is applied to the void346 between the cake core 314 and the finishing mold 304. In the exampleshown, a conduit 348 is connected to each injection port 338, andfinishing compound is injected into each injection port via the conduits348. The conduits 348 may be rigid or flexible. One or more vents (notshown) may be provided for allowing air to exit the finishing mold 304as finishing compound is injected.

In some examples, after the finishing compound has been applied, it maybe hardened, and the seal may then be released, and the finishing mold304 may be removed from the cake core 314 and finishing compound, asdescribed above. In other examples, the support layer may be removedfrom the lining layer before the finishing compounds has been hardened.

In alternate examples (not shown), a seal may not be used. For example,the finishing mold may completely enclose the cake core, and may beopenable to allow the cake core to be inserted therein.

The steps shown with regards to FIGS. 13A to 14B may be carried outautomatically, for example in an industrial setting, or manually.

In the example shown, the conduits 348 are connected to and stop at theinjection ports 338. In other examples (not shown), the conduits maypass through the injection ports 338 and into the void 346, so thatfinishing compound may be injected directly within the void 346. Theconduits 348 may be shaped (e.g. bent, curved, and/or straight) so thatthey reach into various places in the void. The conduits may optionallybe retracted as the finishing compound is injected. The retraction ofthe conduits may be automated, for example as a response to pressure ortiming. Alternatively, the retraction of the conduits may be donemanually.

In any of the examples described above, more than one layer of finishingcompound may be applied to the finishing mold. For example, two layersof finishing compound may be applied to the finishing mold. In someparticular examples, the composition of the outer layer of finishingcompound (i.e. the layer that contacts the finishing mold) may beselected so that it readily fills any voids or conforms to any featuresof the finishing mold, so that decorative details of the finishing moldare shown with clarity. Such a finishing compound may be referred to asa liquid icing, and is described below. The inner layer may optionallybe of another composition, for example a composition that is chosen forflavor.

Further, in any of the above examples, different finishing compounds maybe applied at different locations within the finishing mold. Forexample, an icing of a first color may be injected into the void at afirst location, and an icing of a second color may be injected into thevoid at a second location.

In any of the above examples, prior to the removal of the finishingmold, forces may be applied to the finishing mold to move the finishingcompound within the finishing mold. For example, the forces may beapplied to urge the finishing compound into any spaces or to urge thefinishing compound to conform to any features of the finishing mold. Insome examples, the forces may be applied by vibrating the finishingmold. For example, the finishing mold, containing the finishing compoundand cake core, may be placed on a vibration table. In other examples,blunt forces may be used. For example, the finishing mold, containingthe finishing compound and cake core, may be tapped or hit, or the tableupon which the finishing mold rests may be tapped or hit. In otherexamples, the finishing mold, containing the finishing compound and cakecore, may be spun.

In the examples described above, the support layer of each finishingmold is of a one-piece construction, and may be removed from the lininglayer by lifting it off of the lining layer. In alternate examples, thesupport layer may include a plurality of separate sections, which areassemblage together to form the support layer, and which aredisassemblable from each other to remove the support layer from thefinishing layer. For example, the sections may snap together. Such asupport layer may be useful in kits which form cakes of complicatedgeometries, in which it may not be possible to remove the support layerby lifting it off of the lining layer. Such a support layer may be usedin automated or manual applications.

As mentioned above, in some examples, the kits and methods describedabove may be used to prepare 3-dimensional cakes (i.e cakes that aregenerally not a flat sheet).

The kits described above may be sold for home use, or may be usedcommercially and/or industrially to make finished cakes on alarge-scale. Furthermore, any of the steps described above may beautomated. For example, in FIGS. 13A to 14B, the support mold may bemoved downwardly by an automated system. Further, in examples where thesupport layer is of a multi-piece construction, the support layer may beassembled together by an automated system.

In any of the above examples, the lining layer may be of a variety oftextures, which may be imparted to the finishing compound. For example,the lining layer may be smooth to impart a smooth finish to thefinishing compound. Alternatively, the lining layer may be of a roughtexture to impart a rough finish to the finishing compound.

FIG. 5 shows a core mold 400 in accordance with at least one embodiment.In the example shown, core mold 400 can be use for forming and finishinga cake core to produce a finished cake. As used herein and in theclaims, a “finished cake” is a cake core to which at least finishingcompound is applied.

In at least one embodiment, the material composition of core mold 400provides sufficient rigidity for core mold 400 to retain its shape whenforming and finishing a cake core, and sufficient flexibility to allowthe finished cake core to be easily removed from core mold 400. In oneexample, core mold 400 is made of a silicone material, such as ahigh-temperature, food grade, platinum set silicone having a shorerating of between 20 and 50. Optionally, core mold 400 is similar tolining layer 108 of finishing mold 104, with possibly thicker wallsand/or made with a material having a higher shore rating for increasedrigidity.

In the example shown, core mold 400 includes walls 402 which define acavity 404. In at least one embodiment, cavity 404 can be at leastpartially filled with cake ingredients to form a cake core. Optionally,forming the cake core includes baking the cake ingredients inside of thecore mold 400, e.g. using an oven.

FIG. 16 shows a cross-sectional view of core mold 400 taken along line16-16 in FIG. 15, after forming a cake core 406. In the example shown,cake core 406 has been formed to occupy less than the entire volume ofcavity 404 of core mold 400. In some cases, forming cake core 406 mayinclude trimming upper surface 408 to below the level of upper surface410 of core mold 400. For example, some cake ingredients rise when bakedwhich may cause upper surface 408 to rise to or even above the level ofupper surface 4 0. In this example, the upper surface 408 can be trimmedusing, e.g. a knife, to lower the upper surface 408 to below the levelof upper surface 410. In at least one alternative embodiment, uppersurface 408 of cake core 406 is trimmed, if necessary, only after it isremoved from core mold 400.

After forming cake core 406, core mold 400 and cake core 406 can beseparated. Optionally, cake core 406 is cooled or frozen to increase thestructural integrity of cake core 406 before removing from core mold400. For example, cake core 406 inside of core mold 400 can be cooled ina refrigerator or freezer for a few hours or overnight. In some cases,cake core 406 has sufficient structural integrity and core mold 400 hassufficient flexibility to permit cake core 406 to be removed withoutcooling or freezing cake core 406.

In at least one embodiment, before or after removing cake core 406 fromcore mold 400, a thickness 416 about perimeter 412 of cake core 406 maybe trimmed. FIG. 17 illustrates trimming a thickness 416 about perimeter412 of cake core 406 using a knife 414. In the example shown, a uniformthickness 416 is trimmed from the perimeter 412 of cake core 406.Optionally, thickness 416 may be from about 0.125 inches to 2 inches, orfrom about 0.2 inches to 1 inch or from about 0.3 inches to 0.7 inches.In at least one embodiment, thickness 416 is not uniform and variesabout perimeter 412 of cake core 406.

After removing cake core 406 from core mold 400, finishing compound 418can be applied to core mold 400. Optionally, different finishingcompound (e.g. differently colored finishing compound or finishingcompound having a different taste or texture) can be applied todifferent interior surfaces of core mold 400. For example, core mold 400may include an embossed design (e.g. a flower) onto which finishingcompound may be decoratively applied (e.g. to make white petals and agreen stem). In some cases, one or more of air brushed colors, coloredfinishing compound, and texture can be manually applied to the finishedcake. In one example, substantially all of the finishing compound 418applied to core mold 400 is one uniform color (e.g. white), and color(e.g. by air brushing and/or applying additional colored finishingcompound) and/or textured is manually applied to the finished cake.

FIG. 18 shows cake core 406 being inserted into core mold 400 aftertrimming perimeter 412 of cake core 406 and after applying finishingcompound 418 to core mold 400, in accordance with at least oneembodiment. Cake core 406 is shown being inserted centered with respectto walls 402 of core mold 400. This may provide a layer of finishingcompound 418 between cake core 406 and walls 402. Cake core 406 may beinserted into core mold 400 by an application of force in the directionof arrow 420. Optionally, cake core 406 is pressed into core mold 400until upper surface 408 is at or below the level of upper surface 410 ofcore mold 400. In some cases, excess finishing compound is squeezed outof core mold 400 when cake core 406 is inserted. The excess finishingcompound can be removed.

FIG. 19 shows a cross-sectional view taken along line 19-19 in FIG. 18after cake core 406 has been fully inserted into core mold 400, inaccordance with at least one embodiment. As shown, the materialcomposition and thickness of walls 402 of core mold 400 permit cake core406 to be inserted without walls 402 deforming or bulging by theinteraction of cake core 406 with finishing compound 4 8. In the exampleshown, upper surface 408 of cake core 406 is level with upper surface410 of core mold 400. As shown, cake core 406 is centered in core mold400 such that a layer of finishing compound 418 fills the void betweencake core 406 and walls 402 of core mold 400.

FIG. 20 shows a cross-sectional view taken along line 19-19 in FIG. 18,in accordance with another embodiment. In the example shown, atransitional layer 422 of finishing compound is applied between cakecore 406 and finishing compound 418. In some cases, transitional layer422 may improve adhesion between cake core 406 and finishing compound418. In at least one embodiment, transitional layer 422 includessubstantially the same type of finishing compound as finishing compound418. In at least one alternate embodiment, transitional layer 422includes at least some finishing compound that is substantially adifferent type of finishing compound than finishing compound 418.

In one example, transitional layer 422 is applied by squeezing finishingcompound through a nozzle filling gaps between cake core 406 andfinishing compound 418 which remain after cake core 406 is inserted intocore mold 400. In another example, transitional layer 422 is applied byapplying a layer of finishing compound on top of finishing compound 418,and subsequently inserting cake core 406 into core mold 400. In anotherexample, transitional layer 422 is applied by applying a layer offinishing compound directly to cake core 406 (before or after cooling,if applicable), and subsequently inserting cake core 406 into core mold400. In at least one embodiment, transitional layer 422 is appliedaccording to more than one of the above examples.

In at least one embodiment, perimeter 412 of cake core 406 is nottrimmed before reinserting cake core 406 into a finished core mold 400.In one example, cake core 406 shrinks when prepared (e.g. baked) insideof core mold 400. For example, some cake ingredients (e.g. cakeingredients having high moisture content) shrink when baked.

FIG. 21 shows another example, in which a cake core 406, havingsubstantially the full profile of cavity 404 of core mold 400, is beingreinserted into a finished core mold 400. In this example, applyingfinishing compound 418 to core mold 400 may be limited to applyingfinishing compound 418 to the lower wall 426 of core mold 400.

FIG. 22 shows a cross-sectional view taken along line 22-22 in FIG. 21after cake core 406 is inserted into core mold 400. In the exampleshown, cake core 406 occupies substantially the entire width of cavity404. Finishing compound 418, as shown, is substantially limited to alayer between a lower surface 424 of cake core 406 and a lower wall 426of core mold 400.

After cake core 406 has been inserted into core mold 400 (e.g. in any ofthe above examples), core mold 400 containing at least cake core 406 andfinishing compound 418 may be cooled or frozen to harden cake core 406and finishing compound 418. This may increase the structural integrityof cake core 406 and finishing compound 418 to help with subsequentlyremoving core mold 400 without damaging cake core 406 and finishingcompound 418. In some cases, cake core 406 and finishing compound 418have sufficient structural rigidity and core mold 400 has sufficientflexibility to permit core mold 400 to be removed without damaging cakecore 406 and finishing compound 418.

FIG. 23 illustrates removing core mold 400 from finished cake 428 (acombination of at least cake core 406 and finishing compound 418). Asshown, the selected material composition (e.g. silicone as describedabove) and thickness of core mold 400 permit core mold 400 to beflexibly peeled off of the finished cake 428. In an alternativeembodiment (not shown), core mold 400 includes rigid sidewalls 427 (e.g.made of plastic, nylon, metal or rigid silicone) and a flexible lowerwall 426 (e.g. made of flexible silicone). In this case, core mold 400can be removed from finished cake 428 by applying a force to lower wall426 to deform lower wall 426 inwardly and push finished cake 428 out ofcore mold 400.

In at least one embodiment, a large cake (e.g. having a height greaterthan 6 inches) or a cake having a complex shape (e.g. having undercuts)is prepared as a layered cake by stacking or otherwise combining aplurality of cake layers made according to any one or more of theembodiments described herein. For example, FIG. 24 shows a layered cake430 include three stacked cakes layers 432. In the example shown, eachfinished cake layer 432 has a different size and shape, and was madeusing a different mold or molds (e.g. according to one of theembodiments described herein).

In some cases, a layered cake 430 is prepared by stacking a plurality oflayers 432 of finished cakes (e.g. made according to one or more of theembodiments described herein). Optionally, finishing compound is appliedto an exterior of the layered cake 430 to hide the seams between thelayers 432. In some cases, a layered cake 430 is prepared by stacking aplurality of layers 432 of cake cores (e.g. made according to one ormore of the embodiments described herein). Optionally, finishingcompound 433 is applied between layers 432 to hold the layers 432together.

In at least one embodiment, a layered cake kit includes a plurality ofkits for forming the plurality of layers of cores and/or finished cakes.FIG. 25 shows one example of a layered cake kit 434 including aplurality of different core molds 436. Core molds 436 can be used toprepare cake cores (or finished cakes) for the layers 432 of layeredcake 430. In some embodiments, layered cake kit 434 also includes acorresponding finishing mold (not shown) for each core mold 436 forpreparing finished cake for layers 432.

As mentioned above, various finishing compounds may be used in the abovekits and methods. The finishing compounds may optionally include asetting or firming agent, such as gelatin or cocoa butter. In someexamples, a standard icing may be used, which may include approximately65 wt % to 75 wt % icing sugar, 25 wt % to 30 w. % shortening or fat,and 0 wt % to 10 wt % water. In other examples, a liquid icing may beused, which may include 60 wt % to 65 wt % icing sugar, 23 wt % to 28 wt% shortening or fat, 5 wt % to 10 wt % water, and 0.5 wt % to 2.5 wt %gelatin. The liquid icing may optionally be warmed when it is applied tothe finishing layer, so that it is generally quite fluid, and thencooled after applied to the finishing layer, so that it hardens. Inother examples, a putty icing may be used (mentioned above), which mayinclude 75 wt % to 80 wt % icing sugar, 18 wt % to 23 wt % shortening orfat, and 0 wt % to 3 wt % water. The putty icing may further optionallyinclude a setting/firming agent. In other examples, a high slump icingmay be used, which may include a fat that is quite firm at roomtemperature a medium ratio of sugar, and optionally a setting/firmingagent such as gelatin.

In at least one embodiment, a kit (e.g. kit 100) for preparing a cakemay include one or more chocolate molds. The chocolate molds may be usedto form solid or hollow chocolate shapes. In some cases, the moldedchocolate shapes may be used in conjunction with a cake core or finishedcake. For example, molded chocolate shapes may be placed inside areas ofa cake core or finished cake to provide structural support where needed.

In some cases, a hollow chocolate shape may be hidden inside a cake toprovide a hollow cake a having reduced density and improved structuralintegrity (e.g. as compared with a cross-section of solid cake). Thismay permit a cake to have impressively large outside dimensions, and yeta low weight and smaller net volume for feeding fewer people.

In at least one embodiment, a hollow chocolate shape incorporated into acake may be filled with one or more of cake, candies, chocolates, toys,and gifts for example.
